Topology Discovery
CLI.
Atlasmap discovers hosts on your network, traces connections, and renders the topology as ASCII art in your terminal or as an interactive HTML file you can share. See your infrastructure layout without installing agents on every machine.
$ atlasmap scan --docker

What It Does
Discover. Map. Visualize.
Atlasmap pings subnets, detects live hosts, identifies open services, and traces network paths. The result is a topology map rendered as ASCII in your terminal or as a self-contained HTML file.
Subnet Discovery
Scans CIDR ranges to discover live hosts. Identifies hostnames, open ports, and detected services on each discovered node.
Route Tracing
Traces network paths between hosts to map connectivity. Identifies gateways, hops, and latency between nodes in your topology.
ASCII Output
Renders the topology as clean ASCII art directly in your terminal. Perfect for quick audits, documentation, and sharing in chat.
Interactive HTML
Export as a self-contained HTML file with interactive zoom, pan, and click-to-inspect. Share with your team without any server required.
JSON Export
Export the raw topology data as JSON for integration with other tools, scripts, or documentation pipelines.
Open Source
MIT licensed. Audit the code, contribute, or fork it. Built for transparency and community use.
ASCII Output
Your network. In your terminal.
Run atlasmap scan 10.0.1.0/24 and see your topology rendered as ASCII art. Pipe to a file, paste into a Slack message, or embed in documentation.
Install
One command. Mapping in seconds.
The installer downloads a single binary. No config required to start scanning — just pass a subnet.
Live Topology
Static snapshot? HostAtlas gives you live topology.
Atlasmap gives you a point-in-time network map. HostAtlas gives you a continuously updated Atlas Graph — live topology visualization with real-time metrics, service status, and relationship mapping across your entire infrastructure.
